How can I disable redundant SNMP logging (connection information)?

  • Hi,


    Under normal working conditions, when SNMP Managers query SNMP agents (snmpd) on OMV, several lines of information similar to the following are logged into syslog:
    2015-02-01 21:50:30 Local0 Info 192.168.1.253 Feb 1 21:50:29 nas snmpd[18765]: Connection from UDP: [192.168.1.254]:56711->[192.168.1.253]
    2015-02-01 21:50:25 Local0 Info 192.168.1.253 Feb 1 21:50:24 nas snmpd[18765]: Connection from UDP: [192.168.1.254]:56710->[192.168.1.253]
    2015-02-01 21:50:15 Local0 Info 192.168.1.253 Feb 1 21:50:14 nas snmpd[18765]: Connection from UDP: [192.168.1.254]:56705->[192.168.1.253]
    .....
    As snmpd is typically queried frequently, my syslog will be filled with several such informational lines as this can lead to “noise” and is truly not required.
    How can I disable redundant SNMP logging (connection information)?
    Thank you in advance.

  • This is how I fixed my OMV


    Modify the snmpd file from the following location


    vi /etc/default/snmpd


    change this line:
    SNMPDOPTS="-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid"
    to this:
    SNMPDOPTS="-LS4d -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid"


    LS4d will change the logging to warning and eliminate the snmpd messages from getting logged and going to your syslog server.
